SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent No. 621,197, dated March 14, 1899.

Application fil d October 11, 1898. Serial No. 693,256. (No model.)

To all whmn it may concern:

Be it known that I, JAMES WHITELY ALEX- ANDER, .of Bridgeport, in the county of Belmont and State of Ohio, have invented a new and Improved Smoke-Consumer, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved smoke-consumer which is simple and durable in construction and arranged to draw the smoke, sparks, and cinders from the smoke-box of the boiler into the fire-box to be consumed therein with the burning fuel.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Referenceis to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate correspondingparts in all the figures.

Figure 1 is a side elevation of the improvement as applied to a locomotive-boiler with part of the smoke-box broken out. Fig. 2 is anenlarged rear elevation of the same with part in section, and Fig. 8 is an enlarged rear end elevation of the same with parts in section.

The locomotive-boiler A, on which the improvement is applied, is provided with the usual smoke-box B,into which open the smokeflues leading from the fire-box O. In the bottom of the smoke-box B is formed an opening B, leading to a casing D, from the sides of which extend the suction-pipes E, extending alongside the boiler to the casing F of the fuel-door, through which the fuel is passed to the fire-box O, the casing F extending a distance from said end of the boiler to accommodate the ends of the suction-pipes E, so that the smoke and cinders pass into the casing in front of the door F and directly into the firebox. Each suction-pipe is provided near its rear end with a valve E, and into each pipe near this end extends the nozzle of a pipe G, connected byabranch pipe G with the steamcompartment of the boiler, so that steam under pressure can pass through the pipe G into the pipes G and to the suction-pipes E, so as to create a suction therein to draw the smoke and cinders from the smoke-box B into the casing F and fire-box O. The pipe G is pro vided with a suitable valve G for regulating the amount of steam passing into the suctionpipes E, the draft therein being regulated by the valves E. I

Directly over the opening B in the bottom of the smoke-box B is arranged a bell-shaped deflector I-I, adj ustably held on a rod I and adapted to be secured thereon bya set-screw H, the rod being heldat its upper end in a cross-barJ, attached to the sides of the smoke box, the lower end of the rod resting in a seat formed in the bottom of the casing D.

When the device is to be used, the valves E and G are partly or wholly opened, so that the steam passing into the suction -pipes creates a suction therein, as stated, to draw the smoke and gases from the smoke-box over the deflector H, down into the casing D, and from the latter through the pipes E into the door-casing F and to the fire-box O. The smoke, cinders, and sparks are thus returned in avery simple manner from the smoke-box to the fire-box to be consumed with the burn= ing fuel.

It will be seen that the device is very simple and durable in construction, is not liable to get out of order, and the workings thereof are completely under the control of the fireman or engineer in the cab of the locomotive.

From the foregoing it is evident that the device may be readily applied to other boilers besides locomotive-boilers, as shown and described.

By having the deflector H arranged over the opening B the cinders and sparks are more uniformly distributed. Moreover, as the cross-section is thus reduced at the opening B the velocity of the draft is increased,

carrying the cinders along forcibly and'some-- above said opening and spaced therefrom entirelysoas to form an annular channel around the deflector, pipes leading from the ends of said casing on each side of the boiler to the fire-box, and means for creating a suction in said pipes to draw the cinders and smoke from the smoke-box to the fire-box.

2. In a smoke-consumer, a smoke-box having an aperture in its bottom, a verticallyadjustable deflector flaring toward its lower endand located above said opening so as to form an annular channel around the deflector, a pipe leading from the said opening to the fire-box, and means for creating in said pipe, a suction toward the fire-box.

3. In a smoke-consumer, a smoke-box having an aperture in its bottom, a casing located under the smoke box and communicating therewith through the said opening, an upright rod extending from the bottom of the easing into the smoke-box through the opening thereof, a deflector located in the smokebox and adjustable longitudinally upon said rod, a pipe leading from the casin g to the firebox, and means for creating in said pipe, a suction toward the fire-box.
